基于DEA的江西省农业生产效率时空特征研究

Spatial-Temporal Feature of Agriculture Production Efficiency Based on DEA in Jiangxi Province

采用DEA方法,从县域尺度对江西省2000-2010年间的农业生产效率进行分析,总结得出其规模效率、纯技术效率和综合效率的时空分布特征,结果发现:1)2000-2010年间,江西省的农业综合效率呈现先上升后稍有下降的趋势,其中2006年最高为0.931,2000年最低为0.867;2)从空间分布特征来看,江西省的综合效率,呈现赣中地区最高,赣南地区其次,赣北地区最低的特征;3)由3个农业生产效率值可知,江西省农业生产效率的高低很大程度上依赖于规模效率,而纯技术效率值相对较低,因此要进一步提高研究区域的农业生产效率,需要加大技术上的投入,改进生产技术水平。

DEA model was used to analyze the agriculture production efficiency of Jiangxi Province from 2000 to 2010 in the scale of county,and summarize the special-temporal distribution features of the scale efficiency,pure technical efficiency and the comprehensive efficiency. The results are as follows1） From 2000 to 2010,the trend of agriculture comprehensive efficiency rise apparently first and then slightly drop down,which is up to 0. 931 in 2006,while the minimum is 0. 867 in 2000. 2）From the space distribution characteristics point of view,the value of comprehensive efficiency of Jiangxi Province in Ganzhong Region is the highest,the second is Gannan Region,and Ganbei Region is the lowest. 3） Comparing the three agricultural production efficiency values,it is obviously that the production efficiency of agriculture in Jiangxi Province is largely dependent on the scale efficiency. The value of pure technical efficiency is relatively low. As a result,the methods to further improve the efficiency of the research area of agricultural production are as follow,increasing the technical inputs,renewing the production technology.
